Well it looks like the way to go with the MIL will be the 2 bedroom suite. It is 800 square feet. It has two separate bedrooms (each with a door!!) and then a sofabed pull out in the living room. Sleeps up to 6 total. The suite has three tvs, three phones,two bathrooms (so MIL can have her own). This room is a little more pricey .. but maybe your MIL will pick up the bill !!
The Bi- loft is also an option .. but it looks like the 2nd bedroom is upstairs and a loft, so there for not a door that closes and if people doorstairs are noisy or have lights on I have read on tripadvisor that it can be a problem for some. I personally would just throw a pillow down at them and say SHUT UP !!! But that is just me

I agree. The parking is tight but adequate until you get a few monster vehicles parking in the same area(I wonder about folks depth of perception.) We have checked out a number of places over the years and this place works best for us. With the 6 of us(15-61) the hot breakfast, managers specials, grocery shopping saves us both time and money while we are there. Subtract those expenses from your room rate. I have also made friends with the management over time and last year we paid $139/night mid August just by asking for a discount.
Best of luck,
Jack
